I can't speak to how viable the use of windows as a head node is, but I
do know that LANL had a paper in the last couple of Linux Journals about
building just such a beast, housed in a plastic toolbox. They had
one of their prototypes on display at SC2005. They use a thinkpad as
the head node on their systems. You might want to check with them for
more engineering details.
